Application tiled February '1, 1912. Serial No. 874.-,758.

T o all whom it may concern y Be it known that l, HARRY Lariosinnnn, a citizen of the United States, residing at Poplar Blulf, county of Butler, and State of Missouri, have invented a new and useful Adding and Recording Machine, of which the following is a specification.

T his linvention relates to adding and recording machines and its object is to provide in combination with the recording and operating mechanism, an improved ribbon operating mechanism, and automatic means for reversing the movement of the ribbon.

Another object isto provide ribbon spools and va laterally-movable rotary shaft, with suitable gears whereby the shaft may be entrained with said spools respectively, with provisionfor automatically eli'ecting the lateral movement of the shaft ctfectively to rotate the other spool when the timefor reversing the movement of the ribbon arrives.

Other objects will appear from the following` description frequent reference being made to the accompanying drawings in which I have shown one embodiment of my invention and in which- Figure 1 is a side elevation of a well known adding and recording machine coutaining my improved ribbon mechanism, the case of the machine being in section in order to disclose the mechanism contained therein. Fig. 2 is a plan view illustrating the arrangement of the laterally-movable shaft which operates the ribbon spools. Fig is a sectional view on the line 3 3 of Fig.

Fig. el is a sectional view on the line 4 1 of lig. Fig. 5 is an enlarged view of a part of the spool operating shaft illustrating the driving ratchet and the centering and holding device copcrating with the shaft to prevent said shaft from heilig shifted laterally bythe resistance of the spool shafts. l `igs. 0 and 7 are detailed views of thc centering and holding device which coperates with the spool operating shaft. Fig. 8 is a sectional view of the centering and holding device taken approxmatcly on the line 8 t4 of llig. thc ribbon spools and the operating mechanism. Fig. 10 is a sectional view of on(l of the ribbon spoolsI and its sul'iport. Fig. 11. plan vicw of o ne of the i'ibbon spools. Figs. 12, 13 and 1,41 are detailed views illustrating thc means by which the ratchet wheel Fig. 9 is an enlarged rear view of which rotates the drive shaft also shifts the drive shaft laterally to reverse the movement of the ribbon.

l have illustrated my invention embodied in an adding and recording machine known commercially as the Dalton adding inachine, which is constructed in substantial conformity to the adding department of the combined adding and writing machine constituting the subject-matter of Hopkins Patent No. 1039130, dated September Q4, 1912, the application for which was filed January 24, 1908. ln said machine there is a main shaft l, rocked ythrough operation of a handle or lever 2 and having link connection 3, which, when operated, causes the type-carriers lto be reciprocated adjacent to the platen mounted in the paper carriage 5. The link which is operated by tho/ rock shaft 1 operates a part (l by which the shaft controlling the ribbon spools is rotated through connections hereinafter described.

Near each side `of the machine andy in front of the paper carriage is a ribbon spoolcase or housing` 7, within which the ribbon spools are contained and operated and from which the ribbon is fed across the lnachine near the platen which is mounted in the paper carriage. On the case of the machine below each ribbon spool-case 7 is formed a bearing 8 (Fig. 10). 4In each bearing S is journaled a small shaft 9 having an annular flange 10 operating against the case and preventing),` the shaft from working out. of the bearing. Above thel flanges 10 the shafts 9 have reduced portions 11 on cach of which is a locking pin 12 arranged to engage in a slot or notch in a collar or sleeve 13 fitting over said reduced portion. (,)n the lower end of each of the collars or sleeves lil isa circular plate 14, said plates constituting the lower ends and confining walls of the spools. A. c'vliiulrical spool 1:3 encirclcs each of the collars or sleeves .i3 and is inter-locked with the lower spool-wall` 14, as shown at 10 in Fig. 10. An upper end or confining wall for cach spool is provided in the form of a circular' plate l? having a knob 1S for marnual engagement for purposes of ren'ioval, ctc., said walls or ends being Vinter-lockedv with the cylindrical spool bodies, as shown at 1S). A beveled gear Q0 is attached to the lower end ot cach ofthe spool shafts l), said gears' being within the case of the machine rand constituting the means for rotating the spools mounted on said shafts effectively to move the ribbon across the machine. i

The shait 2l is supported 1n bearings 29.

- removably mounted in the arms 23 attached also be imparted to one of the spool shaftsv effectively to Windl the ribbon onto the spool of said spool shaft so operated and to draw the ribbon from the spool at the opposite side of the machine. A ratchet Wheel 26 is mounted on the shaft 2l having rictional engagement with said shaft of sniiicient strength and resistance to rotate said shaft when the ratchet wheel is rotated. In other words, the ratchet `wlrieel 26 may be rotated independently ot' the shaft 2l but only when the resistance to the rotation 'of the shaft 2l ismuch greater than that encountered when operating the ribbon spools to draw the ribbon from one spool to the other; when the resistance encountered is 'only that epconntered. in operating the ribbon spools o move the ribbon the rictional engagement between the ratchet wheel 2G and the shaft 21 issuilicient to rotate the shaft, especially since the said ratchet wheel is provided with associated cooperating ,)arts''presently described. The ratchet wheel 26 extends into and operates Within a groove 27 in an adjacent member 2S. An arm 25)' is pivotally supported by the shaft 2l and supports the front end of alink 30 having pin-and-slot connection 31 with another link whose rear end is pivotedl to the movable part G which is operated back and forth by the link 3v each operation of the reemding'meehanis-in, including the type-carriers 4: and the controlling handle '2. lhese connections recii'irocate the link composed ot the two parts 30 and BQnt each ope ation of the record.- ing` mechanisn'i. fr lspring 33 connecting the'two parts of the link 30e-32 holds said members extended to the greatest length permitted by the pin-andslot connection 3l and permits the part 3Q to move forwardlyvv independent ot the part 8() when too great resistance is encounterml by said part 30, such, for instance,aswhen the ribbon. spools become locked 'from any canse. A pawl 3l is supported hy the arm 2S) and operates upon the .ratchet wheel QG thereby rotating said ratchet wheel. and the sha't't Q1, with which it is 'friciioimlly engaged, Yforwardly at each operation ol' the recording mechanism. rl`hi`I rotation ol'i the shaft .Zl also rotales the rihbon spool shaft Sl with which said shaft El 1s entrained etlectively to operate the. rm'

bon. Backward rotation of the ratchet Wheel 26 on the shaft 21 prevented by a 4ratchet wheel 26. When the recording mechanism is operated effectively to rotate the ratchet wheel 2G, as above described, the cam 3G, on oneside of said wheel, Will en# gage against the pin 37 on the ,sha tl, which engagement, in addition to the frictional enga (rement between the ratchet wheel.

on said shat 2l, is snliicient to prevent indeW pendent rotation or' the ratchet wheel while4 the ribbon is movable.

l/Vhen one of the ribbonspools becomes filled and the other entirely empty the empty spool, to which the ribbon is attached, can

be rotated no further and the ribbon stretches and revente further rotation oli the filled. spoo with which the operating shaftQl is entrained. Additional ai ing of the recording mechanism, ther results in independent rotation of the r. wheelf on the shaft 2l and this independf ent, rotation of said ratchet wheelq operates the cam 36 against the pin 3T on said shaft 21. ,Since the wheel Qdis not laterallyenoi able and since the shaft 2l is laterally-mow able this operation of the cam 36 against the pin 37 on said shaft 21 moves said shaft 2i laterally in its bearings etlectively to entrain one of the pinions Q5 with the gear 2O connected to the empty. ribbon spool and to disconnect the other pinions .25 from the filled-up ribbon'spool. This lateral more ment of the shaft 2l brings the other pin 3T against the cam 36 on the opposait@ side ot' the wheel 2G so that said pin and said cam cooperate to assist in operating` imlepemient litirotation ot' the ratchet. wheel on the shalt Qllnntil the other ribbon spool becomes lilled and the'shaft is again moved laterally bc- `cause of the resultant locking ot' the hait against further 'rotation nntil disengagcigl from the filled-np spool. This lateral more ment of the shaft Zl, clloctively to reverse the operation of the ribbon. 1t will he observed, is automatically eli'ecl'ed when one spool becomes entirely empty whatever -may be the length of the ribbon.

,ln connection with the shalt 2l l-have provided a centering" and holding` device, which cooperates with (he cams lo to position the said .shall ai each lateral movennnt thereof. and also acts independently to hold the shaft' trom heineY moved by the resistance of the spool sha l't. collar 3S is attached to the shaft 2l. and is provided with peripheral grooves or channels which l'oim an attenul jOnri'i-aled.

ated rib or flange 39 (Figs. 5, 6 and 7). A. yoke or bracket lO is pivoted to a support livhich, in the present instance, is one of the arms 23 beloiv the shaft 21. A triangul'ar hole is formed in each side of the yoke or bracket t() and in said holes a lroller 4 3 is A spring lelis connected to-the yoke or bracket i0`and holds the roller 4:3 in one or the other of the grooves which form the rib When the shaft 2l is moved laterally the rib. 39 moves across the roller 43 to the other side of said roller and the spring` i4 presses the said'roller @c3 against4 the oblique Wall or side of said ribfil) and assists in moving and positioning the shaft 21 until the roller becomes seated in one or the other positions shown in Figs. 6 and 7. This effects the proper connection between the pinions and the Wheels 20, respec' tively, when the shaft 21 is moved laterally.
